Most of the components can be bought for much cheaper at Digi-Key, Jameco, or similar. At Solarbotics you can find the dual AA battery holder and the Mabuchi motor. You can find these components at any good electronic store.

Here is all the parts for the construction the beetle robot.

1. Cut the electric wire in pieces of 6 cm each, 13 times.

Strip 1 cm at each end.

2. Regroup all the components.

3. Solder each wire to each components except the two batteries.

4. Take the battery holder and make a connection to the connection.

This will give a third connection.See picture below,

The blue wire is the third connections

5. Turn the battery holder up side down so the batteries point to the ground. Glue the two switches on the battery holder in a V form.

6. Glue the motor beside each switch so that the shaft touches the ground

7. Take the big paperclip and make the caster like the picture below.

You can make a nice looking caster or a normal one

I prefer the nice one

8. How to make the connection

9. Take the small paper clip and bend them to make antenna.

Glue them to the switches and don't put to much glue.

Add 1 cm of heat shrink to the shaft of each motor.

10. Add the batteries in the battery holder and put it on a flat surface to see your creation take life. Congratulation!
